[FFmpeg-devel] [PATCH 3/3] lavu/hwcontext_qsv: Make sure hardware vendor is Intel for qsv on d3d11va

[Xiang, Haihao]

From: Haihao Xiang <haihao.xiang at intel.com>

When multiple hardware are available, the default one might not be
Intel Hareware. We can use option vendor_id to choose the required
vendor.
